Description
We performed BVRi imaging of the Neutron Star X-ray Binary MAXI J1647-227 (Negoro et al., ATEL #4175; Kennea et al., ATEL #4178, #4192) with the 2.5 m Nordic Optical Telescope, NOT, at the Observatorio del Roque de los Muchachos, La Palma, from 18 to 20th June 2012. The target was calibrated using four different Landolt (1992) standard fields observed during the second night. Our average BVRi magnitudes are: B=20.80+-0.10, V= 20.08+-0.06, R=19.72+-0.07, i=19.00+-0.10; B=20.23+-0.05, V=19.96+-0.04, R=19.60+-0.06 , i=19.34+-0.06 and B=20.44+-0.02, V= 20.09+-0.02, R=19.67+-0.02, i=19.20+-0.04 on June 18, 19 and 20 respectively.

    Convection, rotation, and magnetic activity of solar-like stars from asteroseismology
    During the last decade, our understanding of stellar physics and evolution has undergone a tremendous revolution thanks to asteroseismology. Space missions such as CoRoT, Kepler, K2, and TESS have already been observing millions of stars providing high-precision photometric data. With these data, it is possible to study the convection of stars

    Tales of stellar & binary co-evolution, told by stellar oscillations
    Stellar binarity and stellar oscillations are mostly seen and studied as two separate phenomena. Sometimes, one process is even complicating the analysis of the other beyond the liking of one or the other research community. However, the complete picture painted by the physical constraints provided by the combination of both processes represents a
